About 125 staff and students at a Guam high school are to be tested for tuberculosis after a student at the school tested positive for the disease.
Department of Public Health officials say the student became sick and was hospitalised before Christmas.
The Pacific Daily News reports the student has since been treated and cleared to return to school.
The department says people who shared classes with the student and family and friends will be tested next week.
In 2002 there were 65 cases of TB, meaning there were 40 cases per 100-thousand residents, compared to 5-point-5 on the US mainland and 11-point-9 for Hawaii.
